wordpress - Insert PHP within function -

i have kid theme in wordpress , want insert code @ end of each single post:

<?php the_tags(); ?>

i don't want edit single.php. insert code via functions.php

i found thread , used code in answer: https://wordpress.org/support/topic/insert-info-into-bottom-of-posts#post-3990037

it worked me, cannot figure out how insert php code.

these things tried didn't reflect wanted in front end end:

$content.= '<?php the_tags(); ?>'; $content.= ' the_tags();'; $content.= <?php the_tags(); ?>; $content.= the_tags();

how can alter code in wordpress thread include php?

thank you.

you're attempting concatenate output of the_tags onto $content, the_tags not homecoming anything. when phone call the_tags sends output browser itself.

the_tags pretty much wrapper around get_the_tag_list homecoming content string rather outputting it. try:

$content .= get_the_tag_list();

also, clarify wrong of attempts:

$content.= <?php the_tags(); ?>;

<?php means begin interpreting php, @ point i'm assuming have opened php tags there no need 1 time again , attempting result in error.

$content.= ' the_tags();';

this append literal string the_tags(); onto $content. cannot embed function calls strings this.

$content.= '<?php the_tags(); ?>';

this lastly line combination of 2 issues mentioned. result in literal string <?php the_tags(); ?> beingness appended $content.
